Glossary
A tool that produces finished video files from inputs such as text prompts, scripts, photos, or audio — without filming. Talking-avatar generators are one of the most practical sub-categories.
AI video generators range from open-ended text-to-video models (Sora, Runway, Veo) to focused tools like vlogme.ai that specialize in one job — turning a photo + script into a polished talking-head video.
For most practical work (course intros, sales outreach, product onboarding, social ads) a specialized talking-avatar generator ships in minutes per clip and stays on-message, while open-ended generators are best for cinematic B-roll.
A digital character — usually built from a single photo — whose lips, jaw, and expressions are animated by AI to match a chosen voice or script.
A workflow that turns a written script into a finished video — usually by generating a voiceover, animating a face or scene, and assembling the result automatically.
Generating a moving video from a single still photograph — most commonly by animating the subject's face to speak.
